Introduction
The problem can be solved by using the concepts of current density and drift velocity. Current density can be defined as the current flowing per unit area (area of cross-section).
Mathematically,
Drift velocity is defined as the average velocity attained by the charged particles due to an electric field.
Mathematically it can be defined as
